BACKGROUND

Sleep disorders are extremely common in the general population, withestimates of 15 million adults in the U.S. with persistent insomnia, andanother 24 million adults and children suffering from obstructive sleepapnea. The current model of care is for people to seek consultation withtheir primary care doctor first about their sleep issues. From there,people are referred for sleep studies, sleep specialists, or givenmedications. Treatment is often delayed, involves potentiallyhabit-forming if medications, or is too expensive to pursue.

Smartphones are becoming the predominant link between data and people.Most current smartphones provide a capability to use mobile softwareapplications (apps). A mobile software application (app) can embody adefined set of functionality and can be installed and executed on amobile device, such as a smartphone, a tablet device, laptop computer,or other form of mobile computing or communications device. Conventionalmobile apps are available that focus on one narrow aspect or another ofdifferent sleep problems. However, these conventional mobile apps do notintegrate a set of diagnostic and therapeutic tools to fully assess andtreat a user's sleep disorder. For example, current systems do notintegrate a user's sleep history in a diagnostic and treatment system.Additionally, one may find a mobile app that plays soothing music, oranother that wakes the user up at a particular time, or another thatrecords snoring. However, these systems cannot combine data obtained ina diagnostic phase for use in a sleep disorder treatment phase.

SUMMARY

The various embodiments described herein offer a solution to theproblems identified above by providing an interactive interview with theuser, then guiding users to possible sleep disorder diagnoses andtreatments. If the user shows signs of insomnia, the app instructs theuser in behavioral therapy, provides a sleep log tool to monitorprogress, and gives feedback to the user about their progress, followingestablished clinical guidelines for treatment. If the user shows signsof obstructive sleep apnea, the user may employ the breathingdisturbance monitoring device described herein to measure respiratorypatterns at night. Screening studies for sleep apnea are integratedwithin the app itself All the tools contained in the various embodimentsdescribed herein educate the user about their sleep problem and provideimmediate assistance—with ease of use and for a low cost.

The various embodiments described herein provide a software applicationthat includes among the following features:

-   -   a. An automated and prompted sleep interview similar to an        interview a patient might receive in a doctor's office.    -   b. Feedback to the user based on the user's answers in the        prompted sleep interview.    -   c. Guidance through behavioral treatment programs, including        Stimulus Control Therapy and Sleep Restriction Therapy. The        treatment programs for a particular user are customized and        based on information gathered from the user and diagnoses        automatically determined from the prompted sleep interview.    -   d. A sleep log meter so the user can keep track of sleep        patterns in quantitative way.    -   e. Soundscapes to assist the user to achieve a relaxed state        before bed and whenever the user cannot fall asleep.    -   f. Automated information presentations that describe possible        sleep diagnoses in more detail, typical diagnostic tests,        various treatment options, and the five closest sleep centers to        the user's location.    -   g. Rewards Center where the user can redeem points collected for        keeping sleep logs or for completing other actions to which        incentives are tied. The user can redeem points for prizes, such        as animal dream totems, exclusive musical recordings, additional        soundscapes, and the like.    -   h. Breathing Disturbance Meter integration, which measures        respiratory breathing patterns at night to screen for possible        obstructive sleep apnea.    -   i. All graphs and questionnaires may be exported as PDF files        and emailed to the user and/or a doctor.    -   j. The diagnostic and treatment features of the various        embodiments were designed by a board certified sleep specialist.

The combinations of features described and claimed herein do not existin an integrated and coordinated manner in any other app or softwareproduct with a single focus—to help more people at the lowest costpossible to sleep better and therefore perform better.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of the various embodiments. It will be evident, however,to one of ordinary skill in the art that the various embodiments may bepracticed without these specific details.

In the various embodiments described herein, a system and method forsleep disorder diagnosis and treatment are disclosed. The variousembodiments provide the ability to integrate a set of diagnostic andtherapeutic tools to fully assess and treat a user's sleep disorder in aconvenient and low cost mobile platform. In various embodimentsdescribed in detail below, a software application program is used togenerate and enable the sleep disorder diagnosis and treatment systeminterface using a computer system, a web appliance, and/or a mobiledevice. As described in more detail below, the computer or computingsystem on which the described embodiments can be implemented can includepersonal computers (PCs), portable computing devices, laptops, tabletcomputers, personal digital assistants (PDAs), personal communicationdevices (e.g., cellular telephones, smartphones, or other wirelessdevices), network computers, set-top boxes, consumer electronic devices,or any other type of computing, data processing, communication,networking, or electronic system.

A mobile version of an example embodiment provides a user-friendlyinterface from which the user can easily view and interact with thevarious information presentations and prompts from a mobile device. Asdescribed in more detail below, a mobile software application (app)embodying a mobile version of an example embodiment as described hereincan be installed and executed on a mobile device, such as a smartphone,a tablet device, laptop computer, or other form of mobile computing orcommunications device. In another embodiment, a website can be used as ahosted service provider without installing any software on the mobiledevice. In this embodiment, a user can use the features described hereinjust by directing a browser to the website host through the use of thepreinstalled or installed browser. These embodiments are described inmore detail below. In an example embodiment, a splash screen appearswhenever the user opens or launches the mobile application on the mobiledevice. This splash screen displays a host logo while opening the loginscreen or the live feed.

User log-in functionality in the mobile app provides a user-friendlyuser interface in which the user provides the email address and passwordassociated with the user account. If the user does not have an account,the user can create an account from this user interface. The process ofcreating a user account is simple and only requires the user to providethe following information: name, surname, e-mail address, and password.By completing this information, the user can create an account and getaccess to customized sleep disorder diagnosis and treatment information.

Referring now to FIG. 1, in an example embodiment 100, a system andmethod for sleep disorder diagnosis and treatment are disclosed. In oneexample embodiment, an application or service, typically provided by oroperating on a host site (e.g., a website) 110, is provided to simplifyand facilitate the downloading or hosted use of the sleep disorderdiagnosis and treatment system 200 of an example embodiment. In aparticular embodiment, the sleep disorder diagnosis and treatment system200 can be downloaded from the host site 110 by a user at a userplatform 140. Alternatively, the sleep disorder diagnosis and treatmentsystem 200 can be hosted by the host site 110 for a networked user at auser platform 140. The details of the sleep disorder diagnosis andtreatment system 200 of an example embodiment are provided below.

Referring again to FIG. 1, the sleep disorder diagnosis and treatmentsystem 200 can be hosted by host site 110 and be in networkcommunication with a plurality of user platforms 140. The host site 110and user platforms 140 may communicate and transfer data and informationin the data network ecosystem 100 shown in FIG. 1 via a wide area datanetwork (e.g., the Internet) 120. Various components of the host site110 can also communicate internally via a conventional intranet or localarea network (LAN) 114.

Networks 120 and 114 are configured to couple one computing device withanother computing device. Networks 120 and 114 may be enabled to employany form of computer readable media for communicating information fromone electronic device to another. Network 120 can include the Internetin addition to LAN 114, wide area networks (WANs), direct connections,such as through an Ethernet port or a universal serial bus (USB) port,other forms of computer-readable media, or any combination thereof. Onan interconnected set of LANs, including those based on differingarchitectures and protocols, a router and/or gateway device acts as alink between LANs, enabling messages to be sent between computingdevices. Also, communication links within LANs typically include twistedwire pair or coaxial cable, while communication links between networksmay utilize analog telephone lines, full or fractional dedicated digitallines including T1, T2, T3, and T4, Integrated Services Digital Networks(ISDNs), Digital Subscriber Lines (DSLs), wireless links includingsatellite links, or other communication links known to those of ordinaryskill in the art. Furthermore, remote computers and other relatedelectronic devices can be remotely connected to either LANs or WANs viaa wireless link, WiFi, Bluetooth, satellite, or modem and temporarytelephone link.

Networks 120 and 114 may further include any of a variety of wirelesssub-networks that may further overlay stand-alone ad-hoc networks, andthe like, to provide an infrastructure-oriented connection. Suchsub-networks may include mesh networks, Wireless LAN (WLAN) networks,cellular networks, and the like. Networks 120 and 114 may also includean autonomous system of terminals, gateways, routers, and the likeconnected by wireless radio links or wireless transceivers. Theseconnectors may be configured to move freely and randomly and organizethemselves arbitrarily, such that the topology of networks 120 and 114may change rapidly and arbitrarily.

Networks 120 and 114 may further employ a plurality of accesstechnologies including 2nd (2G), 2.5, 3rd (3G), 4th (4G) generationradio access for cellular systems, WLAN, Wireless Router (WR) mesh, andthe like. Access technologies such as 2G, 3G, 4G, and future accessnetworks may enable wide area coverage for mobile devices, such as oneor more of client devices 141, with various degrees of mobility. Forexample, networks 120 and 114 may enable a radio connection through aradio network access such as Global System for Mobile communication(GSM), General Packet Radio Services (GPRS), Enhanced Data GSMEnvironment (EDGE), Wideband Code Division Multiple Access (WCDMA),CDMA2000, and the like. Networks 120 and 114 may also be constructed foruse with various other wired and wireless communication protocols,including TCP/IP, UDP, SIP, SMS, RTP, WAP, CDMA, TDMA, EDGE, UMTS, GPRS,GSM, UWB, WiFi, WiMax, IEEE 802.11x, and the like. In essence, networks120 and 114 may include virtually any wired and/or wirelesscommunication mechanisms by which information may travel between onecomputing device and another computing device, network, and the like. Inone embodiment, network 114 may represent a LAN that is configuredbehind a firewall (not shown), within a business data center, forexample.

The sleep disorder diagnosis and treatment system can be implementedusing any form of network transportable digital data. The networktransportable digital data can be transported in any of a group of fileformats, protocols, and associated mechanisms usable to enable a hostsite 110 and a user platform 140 to transfer data over a network 120. Inone embodiment, the data format for the user interface can be HyperTextMarkup Language (HTML). HTML is a common markup language for creatingweb pages and other information that can be displayed in a web browser.In another embodiment, the data format for the user interface can beExtensible Markup Language (XML). XML is a markup language that definesa set of rules for encoding interfaces or documents in a format that isboth human-readable and machine-readable. In another embodiment, a JSON(JavaScript Object Notation) format can be used to stream the interfacecontent to the various user platform 140 devices. JSON is a text-basedopen standard designed for human-readable data interchange. The JSONformat is often used for serializing and transmitting structured dataover a network connection. JSON can be used in an embodiment to transmitdata between a server, device, or application, wherein JSON serves as analternative to XML.

In a particular embodiment, a user platform 140 with one or more clientdevices 141 enables a user to access data and provide data for the sleepdisorder diagnosis and treatment system 200 via the host 110 and network120. Client devices 141 may include virtually any computing device thatis configured to send and receive information over a network, such asnetwork 120. Such client devices 141 may include portable devices 144,such as, cellular telephones, smartphones, display pagers, radiofrequency (RF) devices, infrared (IR) devices, global positioningdevices (GPS), Personal Digital Assistants (PDAs), handheld computers,wearable computers, tablet computers, integrated devices combining oneor more of the preceding devices, and the like. Client devices 141 mayalso include other computing devices, such as personal computers 142,multiprocessor systems, microprocessor-based or programmable consumerelectronics, network PC's, and the like. Client devices 141 may alsoinclude other processing devices, such as consumer electronic (CE)devices 146 and/or mobile computing devices 148, which are known tothose of ordinary skill in the art. As such, client devices 141 mayrange widely in terms of capabilities and features. For example, aclient device configured as a cell phone may have a numeric keypad and afew lines of monochrome LCD display on which only text may be displayed.In another example, a web-enabled client device may have a touchsensitive screen, a stylus, and many lines of color LCD display in whichboth text and graphics may be displayed. Moreover, the web-enabledclient device may include a browser application enabled to receive andto send wireless application protocol messages (WAP), and/or wiredapplication messages, and the like. In one embodiment, the browserapplication is enabled to employ HyperText Markup Language (HTML),Dynamic HTML, Handheld Device Markup Language (HDML), Wireless MarkupLanguage (WML), WMLScript, JavaScript™, EXtensible HTML (xHTML), CompactHTML (CHTML), and the like, to display and/or send digital information.In other embodiments, mobile devices can be configured with applications(apps) with which the functionality described herein can be implemented.

Client devices 141 may also include at least one client application thatis configured to send and receive content data or/or control data fromanother computing device via a wired or wireless network transmission.The client application may include a capability to provide and receivetextual data, graphical data, video data, audio data, and the like.Moreover, client devices 141 may be further configured to communicateand/or receive a message, such as through an email application, a ShortMessage Service (SMS), direct messaging (e.g., Twitter™), MultimediaMessage Service (MMS), instant messaging (IM), internet relay chat(IRC), mIRC, Jabber, Enhanced Messaging Service (EMS), text messaging,Smart Messaging, Over the Air (OTA) messaging, or the like, betweenanother computing device, and the like.

As one option, the sleep disorder diagnosis and treatment system 200, ora portion thereof, can be downloaded to a user device 141 of userplatform 140 and executed locally on a user device 141 (e.g., see FIG. 2described below). The downloading of the sleep disorder diagnosis andtreatment system 200 application (or a portion thereof) can beaccomplished using conventional software downloading functionality. As asecond option, the sleep disorder diagnosis and treatment system 200 canbe hosted by the host site 110 and executed remotely, from the user'sperspective, on host system 110. In one embodiment, the sleep disorderdiagnosis and treatment system 200 can be implemented as a service in aservice-oriented architecture (SOA) or in a Software-as-a-Service (SAAS)architecture. In any case, the functionality performed by the sleepdisorder diagnosis and treatment system 200 is as described herein,whether the application is executed locally or remotely, relative to theuser.

Referring again to FIG. 1, the sleep disorder diagnosis and treatmentsystem 200 of an example embodiment is shown to include a sleep disorderdiagnosis and treatment system database 103. The database 103 is used inan example embodiment for data storage of information related to thesleep disorder diagnosis and treatment of users, the sleep logs ofusers, communications between users and host representatives, shareddocuments, images, soundscapes, metadata, and the control data formanaging the user interactions and the associated user interfaces. Itwill be apparent to those of ordinary skill in the art that the database103 can be used for the storage of a variety of data in support of thesleep disorder diagnosis and treatment system 200 of an exampleembodiment.

Referring to FIG. 2, an alternative embodiment 101 is shown in which thesleep disorder diagnosis and treatment system 200 and associateddatabase 103 can be downloaded and executed locally at a user device 141of user platform 140. In other embodiments, portions of system 200and/or database 103 can be executed locally at a user device 141 of userplatform 140 or executed remotely at the host site 110. In each of theseimplementations, the functionality and structure of the sleep disorderdiagnosis and treatment system 200 of an example embodiment is similarto the example embodiments described herein.

Referring again to FIGS. 1 and 2, an example embodiment is shown toinclude a sleep disorder diagnosis and treatment system 200. Sleepdisorder diagnosis and treatment system 200 can include a sleep disorderdiagnostic module 210, a sleep disorder treatment module 220, aBreathing Disturbance Meter integration module 230, a reports module240, a user account management module 250, and an administrativemanagement module 260. Each of these modules can be implemented assoftware components executing within an executable environment of sleepdisorder diagnosis and treatment system 200 operating on host site 110or user platform 140. Each of these modules of an example embodiment isdescribed in more detail below in connection with the figures providedherein.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is shown to include asleep disorder diagnostic module 210. The sleep disorder diagnosticmodule 210 can be used to query information from a user and to use theinformation to make a sleep disorder diagnosis. In particular, the sleepdisorder diagnostic module 210 can be used to present, prompt, andprocess user input on various user questionnaires. The userquestionnaires include sleep-related interview questions and a STOPBANGquestionnaire. The STOPBANG questionnaire screens for signs ofObstructive Sleep Apnea (OSA). STOPBANG is an acronym representing thesymptoms that can be indicative of OSA: Snoring, Feeling Tired, Observedpauses in breathing, High blood Pressure, Body mass index greater than35, Age greater than 50, Neck circumference greater than 40 cm (16 in),Male Gender, or post-menopausal female. Three or more positive answersfrom the user on the STOPBANG questionnaire are considered potentiallyindicative of OSA.

The sleep disorder diagnostic module 210 can be configured to generate auser interface to prompt a user for input on various questionnairesrelated to the user's sleep patterns. Based on the user's input, thesleep disorder diagnostic module 210 can determine whether or not theuser is showing signs or symptoms of common sleep disorders. Thesequestionnaires are not designed to provide a certain diagnosis. Rather,the sleep disorder diagnostic module 210 can process the user responsesand automatically determine if the user is showing signs that suggest apossible sleep disorder or a possible sleep-related breathing problem.In this case, the sleep disorder diagnostic module 210 can signal thesleep disorder treatment module 220 to suggest particular sleep disordertreatments or OSA-related treatments. The sleep disorder diagnosticmodule 210 can be configured to store the user's responses to enable theuser to share the responses later with a health care provider. The sleepdisorder diagnostic module 210 can also be configured to use thesequestionnaires and related responses to start a discussion with theuser's health care provider on associated sleep issues to determinewhether a particular treatment is needed. If treatment is indicated, thesleep disorder treatment module 220 can be configured to recommend atype of treatment.

Referring now to FIG. 3, an example embodiment, implemented as a mobiledevice application (mobile app), shows a splash screen or home displayscreen of the user interface of the example embodiment. The home displayscreen is displayed on a user's mobile device when the mobile app islaunched. FIG. 4 illustrates an example embodiment, implemented as amobile app, which shows an initial questionnaire display screen of theuser interface of the example embodiment. The initial questionnairedisplay screen can be presented when the user activates a particularicon presented in the home display screen.

FIGS. 5 through 8 illustrate an example embodiment, implemented as amobile app, which shows various questionnaire display screens of theuser interface of the example embodiment. The series of questionnairespresented by the sleep disorder diagnostic module 210 prompt the appuser for basic demographic information, such as age and date of birth.The various questionnaires also contain questions related to the user'ssleep habits, such as the user's typical bedtime and whether the usertakes any medications before bed. These are important questions that canaffect the quality of sleep. The sleep interview presented and managedby the sleep disorder diagnostic module 210 serves as a starting pointfor a discussion and potential diagnosis of the user's sleep patterns.Based on the user's input, the sleep disorder diagnostic module 210 candetermine whether or not the user is showing signs or symptoms of commonsleep disorders. The sleep disorder diagnostic module 210 can signal thesleep disorder treatment module 220 to suggest to the user and/or selectfor the user particular sleep disorder treatments or OSA-relatedtreatments.

Referring to FIG. 8, the sleep disorder diagnostic module 210 can alsobe used to present, prompt, and process user input on an EpworthSleepiness Scale. The Epworth Sleepiness Scale (ESS) is a scale intendedto assess daytime sleepiness that is measured by use of a very shortquestionnaire. The ESS measures how likely the user is to fall asleep asrated on a scale from 0 to 3, with 0 being not at all likely and 3 beingvery likely. A cumulative score of ten or higher on this scale suggeststhat the user is abnormally sleepy, and may point to an underlying sleepdisorder. This can be helpful in diagnosing sleep disorders. The ESS wasintroduced in 1991 by Dr. Murray Johns of Epworth Hospital in Melbourne,Australia.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is shown to include asleep disorder treatment module 220. The sleep disorder treatment module220 can be used to suggest to the user and/or select for the userparticular sleep disorder treatments or OSA-related treatments based onthe user responses captured and processed by the sleep disorderdiagnostic module 210. In an example embodiment, these sleep disordertherapies or treatments can include: 1) behavioral therapies, 2)stimulus control therapy (SCT), 3) sleep restriction therapy (SRT),sleep logs, and sleep efficiency assessments, and 4) soundscapes. Thesevarious therapies as implemented by the sleep disorder treatment module220 of an example embodiment are described in more detail below.

Behavioral therapies are treatments that focus on changing a person'sbehavior in order to treat a condition. The goal of behavioral therapyis to reinforce beneficial behaviors and discourage behaviors that areharmful or unhelpful. Behavioral therapies encourage the user to createhealthy habits and to break unhealthy ones.

Behavioral therapy for insomnia may include a cognitive component, andthus is termed Cognitive Behavioral Therapy, or CBT. CBT is designed tochange behaviors by focusing on how people think and feel about theirbehaviors and their disorder. CBT is meant to address negative emotions,such as anxiety or depression that may be associated with having adisorder. CBT also explores the thought processes that people go throughwhile engaging in unhealthy behaviors and habits, which may indicate whythey engage in those behaviors. The goal of CBT is to address the rootcauses of unhealthy behaviors and habits (i.e., negative emotions andthought processes), so that these behaviors can be replaced byhealthier, more positive ones. The sleep disorder treatment module 220can be used to guide the user through various CBT treatments based onthe assessment of their condition as determined by the sleep disorderdiagnostic module 210. The example embodiment focuses on behavioraltherapies because these therapies are safer and longer-lasting thansleep medications, and may be started or re-started at any time. Incontrast to some types of sleeping pills or other medications,behavioral therapy does not result in a “tolerance” that limitscontinued benefit. The sleep disorder treatment module 220 recognizesthat changing established behaviors is very difficult. That's why theapp provides positive feedback to encourage users to keep trying. Thesleep disorder treatment module 220 includes several therapies thatteach users to help themselves sleep better. The sleep disordertreatment module 220 also presents, prompts, and retains sleep logs sousers can keep track of their sleep disorder treatment progress. Thesleep logs and the related reports are generated by the sleep disordertreatment module 220 and the reports module 240. The goal of the variousembodiments and treatment strategies is to help increase the quality ofsleep in meaningful and lasting ways.

FIG. 9 illustrates an example embodiment, implemented as a mobile app,which shows a stimulus control therapy display screen of the userinterface of the example embodiment. As part of the treatment or therapyoptions provided by the sleep disorder treatment module 220, a StimulusControl Therapy, or SCT, is used to treat insomnia. In the exampleembodiment, there are five main principles of SCT:

-   -   a. Go to bed when sleepy, not when you think you should go to        bed.    -   b. Get out of bed when not sleeping. Do not stay in bed for more        than 15-20 minutes, even if you are actively trying to sleep.    -   c. No naps.    -   d. Use bed and bedroom for sleep (or sexual intimacy) only.    -   e. Maintain a regular wake-up/get-up time (on weekdays,        weekends, and holidays).

One of the goals of SCT is to help the user associate the bed andbedroom with sleep rather than the inability to sleep. Another goal isto help the user break habits that keep the vicious cycle of insomniagoing, such as staying in bed half of the day to try to “catch up” onlost sleep. SCT helps the user to create new, healthy habits, andencourages the user to maintain a regular sleep/wake cycle. As part ofthis encouragement, the sleep disorder treatment module 220 guides theuser through a set of display screens, information presentations, andprompts. For example, FIG. 9 illustrates how the user can transitionfrom the home display screen to a set of SCT display screens. The SCTdisplay screen section allows the user to review the SCT guidelines andreminds the user of the guidelines before bedtime. The user is promptedto create, follow, and assess their sleep logs using SCT to determine iftheir sleep problems can be resolved with this treatment intervention.In a particular embodiment, the sleep logs can be accessed through thereports page.

FIG. 10 illustrates an example embodiment, implemented as a mobile app,which shows a sleep restriction therapy display screen of the userinterface of the example embodiment. As part of the treatment or therapyoptions provided by the sleep disorder treatment module 220, a nextlevel of behavioral therapy for insomnia is Sleep Restriction Therapy(SRT). SRT is a treatment program that uses controlled sleep deprivationas a therapy. Sleep deprivation is used as a tool to help the user fallasleep and stay asleep. In a typical treatment scenario as guided by thesleep disorder treatment module 220, the user can begin by choosing anSRT program with seven hours of sleep a night or an SRT program with sixhours of sleep a night. If the user has already started SRT and is inthe middle of an SRT monitoring period, the user cannot start a newprogram. It will be apparent to those of ordinary skill in the art thatSRT programs with other sleep time periods (e.g., other than six orseven hours of sleep a night) can also be implemented. As part of theSRT program, the user is prompted to set their desired wake-up time asguided by the sleep disorder treatment module 220. Then, the sleepdisorder treatment module 220 can assign a bedtime for the user that issix or seven hours prior to the desired wake-up time (depending on theSRT program time period selected by the user). The sleep disordertreatment module 220 can remind the user to wind down an hour beforeassigned bedtime, so that the user will be calm and not over-stimulatedwhen they try to go to sleep.

FIGS. 11 and 12 illustrate an example embodiment, implemented as amobile app, which shows sleep log display screens of the user interfaceof the example embodiment. As guided by the sleep disorder treatmentmodule 220, the user can enter their sleep log information by clickingon the right upper corner of a reports page screen presented by thereports module 240. Each morning, the user can use the sleep log toindicate when they got into bed and when they got out of bed, and whenthey actually fell asleep and when they woke up. As shown in FIG. 11,the user can make these entries in the sleep log by sliding the iconsalong the bars as shown. Once the user enters this information, thesleep disorder treatment module 220 can highlight in dark blue the hoursthe user was in the bed as shown in FIG. 11. If the user experiencedawakenings in the middle of the night, the user may tap on each of thehighlighted hour-long units individually to add details, such as theexact time the user woke up, how long the user was awake, and whatoccurred during each awakening as shown in FIG. 12. Using all theinformation entered into the sleep log by the user, the sleep disordertreatment module 220 can calculate the user's sleep efficiency. In anexample embodiment, the sleep efficiency can be calculated as thepercentage of time the user was in bed relative to the time spent by theuser actually sleeping. The goal for nominal sleep efficiency is apercentage equal to or greater than 85%.

Although improvement in sleep quality is the ultimate goal for mostpeople, improvement in sleep efficiency is a primary goal. Sleepefficiency is the sleep feature directly changeable by changing aperson's behavior. It turns out that for most people, improvement insleep quality follows improvement in sleep efficiency. If this is notthe case, then another sleep problem may be present, like OSA or anotherdiagnosis.

Once the user achieves a consistent 85% sleep efficiency for two weeksas guided and monitored by the sleep disorder treatment module 220, theuser is prompted to lengthen their sleep period gradually. In support ofthis feature, the sleep disorder treatment module 220 can automaticallyprompt the user to go to bed 15 minutes earlier every two weeks. The SRTtreatment is complete once the user reaches and maintains an 85% sleepefficiency and feels generally refreshed during the day. The user willhave then learned how much sleep they need to feel refreshed. Noteveryone needs the mythic “eight hours of sleep per night.” Some peopleneed more sleep and others need less sleep. The sleep disorder treatmentmodule 220 is designed to accommodate a variety of sleep patterns in avariety of different users.

The sleep disorder treatment module 220 is designed to be used as asleep maintenance tool as well, even after improvement in sleep patternsis achieved. The sleep disorder treatment module 220 can prompt users tokeep daily sleep logs. If the user's sleep efficiency begins to fall,the sleep disorder treatment module 220 can offer another round of SRTor other therapy, starting from the beginning. Also, if a seven hoursleep restriction period does not improve the user's sleep efficiency,the user can be offered a six hour sleep restriction period.

It is important to note that Sleep Restriction Therapy may make the userfeel worse before feeling better. This is because the SRT treatmentremoves the current “sleep coping mechanism” being used, and replaces itwith a specified sleep schedule purposely meant to initially cause sleepdeprivation. If the user sticks with the SRT treatment program, thesleep deprivation lessens and the user will start sleeping and feelingbetter. In a particular embodiment, a Rewards Center is provided wherethe user can redeem points collected for keeping sleep logs or forcompleting other actions to which incentives are tied. The user canredeem points for prizes, such as animal dream totems, exclusive musicalrecordings, additional soundscapes, and the like. Additionally, anexample embodiment can provide automated information presentations thatdescribe possible sleep diagnoses in more detail, typical diagnostictests, various treatment options, and the five closest sleep centers tothe user's location.

FIG. 13 illustrates an example embodiment, implemented as a mobile app,which shows a soundscape display screen of the user interface of theexample embodiment. The soundscape display screen offers the user avariety of selectable soundscapes that can be played when the user goesto sleep or awakens. The soundscapes are audio clips of calming soundsand relaxing music, as well as meditations to help the user relax at thebeginning or end of their day.

FIGS. 14 through 16 are processing flow charts illustrating an exampleembodiment of a method as described herein. In the manner describedabove, the sleep disorder diagnostic module 210 and the sleep disordertreatment module 220 guide the user through a process of sleep disorderdiagnostic assessment and sleep disorder treatment options customizedfor the particular user. As a result, the user achieves improved sleepefficiency.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is shown to include abreathing disturbance meter integration module 230. The breathingdisturbance meter integration module 230 can be used to detect an OSAcondition or other sleep-related condition in a patient. The breathingdisturbance meter integration module 230 is in wireless datacommunication with a breathing disturbance metering system described inmore detail below.

Because the vast majority of people with sleep apnea have not yet beendiagnosed, two barriers to sleep apnea detection may be the cost andaccessibility of testing. After interpreting thousands of sleep studies,both lab and home studies, the inventor herein determined that apatient's sleep apnea can be detected the majority of the time in asingle abdominal effort channel, wherein the breathing patterns of apatient are captured by a breathing disturbance metering system.

FIGS. 17 and 18 illustrate charts of the breathing patterns of a patientas captured by a breathing disturbance metering system of an exampleembodiment. As shown in FIG. 17, a sleep apnea condition is a 90% orgreater decrease in the breathing airflow of a sleeping person lastingten seconds or longer. As shown in FIG. 18, a sleep hypopnea conditionis a 30% or greater decrease in airflow (from an established baseline)lasting ten seconds or longer. By monitoring the breathing patterns of asleeping person, the sleep apnea condition and sleep hypopnea conditioncan be detected. The breathing disturbance metering system and breathingdisturbance meter integration module 230 can be used to detect, measure,assess, and respond to the potential OSA conditions present in a patientbeing monitored. The details of this system in an example embodiment aredescribed below.

FIG. 19 illustrates an example embodiment of the components of thebreathing disturbance metering system 500 of an example embodiment. Asdescribed herein, the breathing disturbance metering system 500 can alsobe denoted the sleep metering system or on-body device 500. Thebreathing disturbance metering system 500 can include a chest expansionmeasuring device 510 and/or a movement detection device 520. Breathingmonitors are well-known in the art. The chest expansion measuring device510 and/or the movement detection device 520 serve to detect themovements of the chest cavity during the normal breathing cycles of aperson. Once the breathing disturbance metering system 500 is calibratedto the normal breathing patterns of a particular individual, the degreeof chest cavity movement can correlate to the volume of air respired foreach breath. As explained above, anomalies in the breathing patterns ofa particular individual can correlate to variations in the degree ofchest cavity movement in a series of breaths over a given time period.In an example embodiment, the movement detection device 520 can includea level that can measure degrees of movement up and down or side toside.

These variations in breathing patterns can be aggregated into abreathing disturbance index (BDI). Because the breathing disturbancemetering system is not measuring airflow, we derived new terminology toguide the development of a device able to measure abnormalities of one'sbreathing pattern based on abdominal movements. Respiratory effortreduction events, or RERE's, are defined as a >=30% reduction inamplitude of a preceding abdominal effort waveform, lasting 10 secondsor longer or compared to a running baseline over a pre-definedtimeframe. A respiratory effort exaggeration event (REEE) is an increasein a respiratory waveform of 150% to 400% over baseline. A REEE is notcounted if immediately adjacent to a RERE to avoid double scoring thesame event. A RERE that is 10-29% reduced from baseline but accompaniedby a >=3% fall in O² saturation is counted as an event. In general, theBDI for a particular subject can be determined from the generalequation: BDI=#RERE's+#REEE's/total recording time in hours. Segments ofdata artifacts are identified and removed from the equation.

In the example embodiment, the BDI can be computed as follows:

${BDI} = \frac{{\# \; {{RERE}'}s} + {\# {{REEE}'}s}}{\# {hours}\mspace{14mu} {of}\mspace{14mu} {testing}\text{/}{recording}\mspace{14mu} {time}}$

In an example embodiment, the breathing disturbance metering system 500can use clock 540 to measure a start and stop time. Initially, the usercan press a button on the device 500 to activate the device 500 whenthey retire to the bed. In the morning, the user can press a button todeactivate the device 500 after they wake up. After activation, thebreathing disturbance metering system 500 can sample the user'sbreathing patterns over pre-configured time periods (sampling period).For example, the breathing disturbance metering system 500 can beconfigured to sample the user's chest cavity movement (i.e., breathingpattern) for a five minute sampling period. During this sampling timeperiod, the breathing disturbance metering system 500 can record theuser's breathing patterns and save this data in the memory 560. At theend of the five minute sampling period, the breathing disturbancemetering system 500 can enter a low power mode (rest period) to savepower. At a configurable time later (e.g., 15 minutes), the breathingdisturbance metering system 500 can start a new five minute samplingperiod during which a new set of breathing pattern data is gathered andretained in memory 560. Each set of breathing pattern data is timestamped with the current or relative time/date. In this manner, thebreathing disturbance metering system 500 can gather breathing patterndata for the user over the entire night. As the breathing pattern datafor a particular user is gathered, the breathing disturbance meteringsystem 500 can use the processor 550 to scan the data for patternsconsistent with apnea or hypopnea conditions. The processor 550 canscore any detected respiratory effort reduction or exaggerationcondition (e.g., RERE or REEE) for a level of severity. The respiratoryeffort detection data and related scoring can also be stored in thememory 560. It will be apparent to those of ordinary skill in the artthat a variety of related data can also be generated and retained. Itwill also be apparent to those of ordinary skill in the art thatdifferent sampling periods and/or rest periods can be used for aparticular embodiment. Periodically throughout the night or thefollowing morning, the breathing disturbance metering system 500 canestablish wireless data communications with the breathing disturbancemeter integration module 230 and upload the data saved in memory 560 toa memory in the user platform 140. A wireless transceiver and mobiledevice interface 570 is provided in the breathing disturbance meteringsystem 500 to enable this data communication. An energy storage device(e.g., a battery) 580 is provided in the breathing disturbance meteringsystem 500 to power the system. In a particular embodiment, a soundcapture device (e.g., a microphone) 530 can be used to record the soundsmade by the user during a sleep cycle. These sounds can include snoring,which can also be an indicator disrupted sleep. For example, a decibelvariation in a periodic manner can be consistent with sleep disorderedbreathing. In this manner, the sleep disorder diagnosis and treatmentsystem 200 of an example embodiment can obtain real-time data related tothe sleeping patterns of a user and data related to potential OSAconditions present in a patient being monitored.

FIG. 20 illustrates the thoracic cage of a human and the relativeplacement of the breathing disturbance metering system 500 of an exampleembodiment. As shown in FIG. 20, the breathing disturbance meteringsystem 500 can be positioned for data recording at the top of the user'sabdomen with the top of the device positioned at the bottom of theuser's sternum. The breathing disturbance metering system 500 can beheld in place with a belt or straps 502.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is shown to include areports module 240. The reports module 240 can be used to presentinformation to a user in the form of tabular or graphical reports. FIGS.21 through 25 illustrate an example embodiment, implemented as a mobileapp, which shows various report display screens of the user interface ofthe example embodiment. In support of a variety of tabular reports, thereports module 240 can present a Sleep Log Report showing a list ofnightly summaries of information from the user's sleep logs, such as thetime the user went to sleep, total number of awakenings during thenight, and how long the user slept. The Activity Report shows a list ofnightly details about nighttime awakenings, such as why the user woke upand how long the user was awake.

In support of a variety of graphical reports, the reports module 240 canpresent several report formats in the form of graphs. For example, theuser can look at the number of awakenings and sleep efficiency on anightly basis. The user can also look at the average number ofawakenings and average sleep efficiency over a specified period of time.This allows the user to look at detailed nightly data, as well astrends, and determine whether or not progress is being made in a sleepdisorder treatment program.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is also shown to include auser account management module 250. The user account management module250 can be used to create and maintain a user account with the sleepdisorder diagnosis and treatment system 200. The user account managementmodule 250 can also be used to configure user settings, create andmaintain a user/user profile, and otherwise manage user data andoperational parameters for the sleep disorder diagnosis and treatmentsystem 200. In the example embodiment described herein, a user canregister as an identified and authenticated user in order to interactwith system 200 and receive sleep disorder diagnosis and treatment. Theregistered user can enter their name, email address, and other personalinformation. Once this information is entered, a user account is createdand the user can interact with system 200 and receive sleep disorderdiagnosis and treatment.

Referring again to FIGS. 1 and 2, the sleep disorder diagnosis andtreatment system 200 of an example embodiment is shown to include anadministrative management module 260. The administrative managementmodule 260 can be used by an agent of the sleep disorder diagnosis andtreatment system 200 to manage user accounts and to manage the sleepdisorder diagnosis and treatment system. The administrative managementmodule 260 can also be used to enforce privacy protections and contentcontrols for users. Moreover, the administrative management module 260can also be used to generate and/or process a variety of analyticsassociated with the operation of the sleep disorder diagnosis andtreatment system 200. For example, the administrative management module260 can generate various statistical models that represent the activityof the community of users and related diagnoses and treatments. Theseanalytics can be shared, licensed, or sold to others under strictprivacy protections and/or as data that has been processed to removepersonal user information.

Although the various user interface displays provided by the exampleembodiments described herein are nearly infinitely varied, severalsample user interface displays and sequences are provided herein and inthe corresponding figures to describe various features of the disclosedembodiments. These sample user interface displays and sequences aredescribed herein and in the accompanying figures.

FIG. 28 shows a diagrammatic representation of a machine in the exampleform of a computer system 700 within which a set of instructions whenexecuted may cause the machine to perform any one or more of themethodologies discussed herein. In alternative embodiments, the machineoperates as a standalone device or may be connected (e.g., networked) toother machines. In a networked deployment, the machine may operate inthe capacity of a server or a client machine in server-client networkenvironment, or as a peer machine in a peer-to-peer (or distributed)network environment. The machine may be a personal computer (PC), atablet PC, a set-top box (STB), a Personal Digital Assistant (PDA), acellular telephone, a web appliance, a network router, switch or bridge,or any machine capable of executing a set of instructions (sequential orotherwise) that specify actions to be taken by that machine. Further,while only a single machine is illustrated, the term “machine” can alsobe taken to include any collection of machines that individually orjointly execute a set (or multiple sets) of instructions to perform anyone or more of the methodologies discussed herein.

The example computer system 700 includes a data processor 702 (e.g., acentral processing unit (CPU), a graphics processing unit (GPU), orboth), a main memory 704 and a static memory 706, which communicate witheach other via a bus 708. The computer system 700 may further include adisplay unit 710 (e.g., a liquid crystal display (LCD), plasma, or acathode ray tube (CRT)). The computer system 700 also includes an inputdevice 712 (e.g., a keyboard), a cursor control device 714 (e.g., acomputer mouse or trackpad), a disk drive unit 716, a signal generationdevice 718, and a network interface device 720.

The instructions 724 may also reside, completely or at leastpartially, within the main memory 704, the static memory 706, and/orwithin the processor 702 during execution thereof by the computer system700. The main memory 704 and the processor 702 also may constitutemachine-readable media. The instructions 724 may further be transmittedor received over a network 726 via the network interface device 720.While the machine-readable medium 722 is shown in an example embodimentto be a single medium, the term “machine-readable medium” should betaken to include a single non-transitory medium or multiplenon-transitory media (e.g., a centralized or distributed database,and/or associated caches and servers) that store the one or more sets ofinstructions. The term “machine-readable medium” can also be taken toinclude any non-transitory medium that is capable of storing, encodingor carrying a set of instructions for execution by the machine and thatcause the machine to perform any one or more of the methodologies of thevarious embodiments, or that is capable of storing, encoding or carryingdata structures utilized by or associated with such a set ofinstructions. The term “machine-readable medium” can accordingly betaken to include, but not be limited to, solid-state memories, opticalmedia, and magnetic media.

FIG. 29 illustrates an example embodiment of the components of the sleepmetering system 500 of an example embodiment. As shown, an exampleembodiment can include a housing 505 to contain an array of sensors fordetecting various conditions and events in a human subject wearing thesleep metering system 500 around their chest. The housing 505 isconfigured in an elongated low profile design to minimize the discomfortof a subject wearing the sleep metering system 500 during sleep. A beltor strap 510 is coupled to the housing 505 in a loop to enable the sleepmetering system 500 to be attached to the chest of a subject while thesubject is sleeping. The housing 505 of the sleep metering system 500 isconfigured to include an array of sensors including: an accelerometer,gyroscope, or other motion detection device 520 to detect and measuremovement and body position of the subject wearing the sleep meteringsystem 500; and a microphone or other sound detection device to detectand measure a sound level or snoring event of the subject wearing thesleep metering system 500. The housing 505 of the sleep metering system500 is also configured with an electrical connector 507 to provide anelectrical/data interface with additional sensors of the array ofsensors. In an example embodiment, the additional sensors coupled to thehousing 505 via connector 507 can include: a pulse oximeter device 532to detect and measure a level of arterial oxygen saturation (SpO2) inthe blood and the heart rate of the subject wearing the sleep meteringsystem 500; and other biomedical devices 534 to detect and measure otherconditions and events (e.g., temperature, pressure, chemical or acidityconcentration, blood viscosity, biological magnetic field, galvanic skinresponse (GSR), wireless interfaces to implanted electromechanicaldevices, pacemakers, implanted insulin pumps, and the like) in a subjectwearing the sleep metering system 500.

FIGS. 30 and 31 illustrate an example embodiment of the inductive beltcomponent of the sleep metering system 500 of an example embodiment. Theadditional sensors of the array of sensors of the sleep metering system500 can also include a chest expansion measuring device or a device tomeasure respiratory effort 510. In an example embodiment, an inductivebelt attached to the housing 505 is provided for this purpose. Therespiratory effort detection device 510 can be used to detect andmeasure airflow and respiratory effort in the subject. The raw sensordata from each of these sensors of the sensor array can be transferredto a processor 550 of the sleep metering system 500. The processor 550can pre-process the raw sensor data (e.g., filter, sequence, timestamp,normalize, packetize, etc.) for subsequent transfer to a central server110 via the wireless transceiver 570. The pre-processing performed bythe processor 550 can also include signal processing to removeundesirable noise from the raw sensor data. The pre-processing performedby the processor 550 can also include filters to reject or removeinvalid sensor data that may be received when the sleep metering system500 is detached from the subject or when the subject is awake and notready to activate the sensor data recording and processing functions ofthe sleep metering system 500.

FIGS. 32 and 33 illustrate an example embodiment of the flow ofpre-processed sensor data signals and processed sensor data from thesleep metering system 500 to a networked server 110 for furtherprocessing and scoring and for networked access by authorized healthcareproviders. As shown in FIGS. 32 and 33, the sleep metering system 500being worn by a subject (e.g., on-body device 500) can capture andpre-process a variety of sensor data from the sensor array of the sleepmetering system 500. For example as described above, the sleep meteringsystem 500 can detect, measure, and transmit pulse data, Sp02,respiratory effort data, breathing pattern data, airflow data, snoringdata, motion data, body position data, and other biomedical metrics andsensor data obtained from a subject wearing the sleep metering system500. This sensor data can be pre-processed by the sleep metering system500 in the manner described above. Additionally, portions of the sensordata or combinations of the sensor data can be arranged into datachannels for scoring, which can be configured for display in charts orgraphs as shown for several examples in FIGS. 34 through 39 anddescribed below.

Referring still to FIGS. 32 and 33, the sleep metering system 500 canperiodically or upon request transfer blocks of the sensor data to acentral server (cloud server) 110 via a wireless data connection andnetwork 120. As shown in FIG. 33, the sleep metering system 500 can alsosend the sensor data via a wireless hub 610, which can forward thesensor data to the central server 110 for further processing andscoring. The scoring of the sensor data by the server 110 is describedin detail above. The server 110 can also record the received sensor datato maintain a time-stamped historical record or recording of thereceived sensor data. The sensor data can also be annotated withmetadata, such as timestamps, subject identification or demographicdata, etc. The scored, recorded, and annotated sensor data for theparticular subject (e.g., the subject's sleep data) can be maintainedand stored in a cloud data storage device 103. The subject's sleep datacan be anonymized to remove specific identifying information related tothe particular subject and thereby make the retention and accessibilityof the sleep data compliant with the Health Insurance Portability andAccountability Act of 1996 (“HIPAA”). Given the implementation of asufficient level of data access security, the sleep data can be madeaccessible to authorized healthcare providers via a secure data networkconnection as shown in FIG. 32. The authorized healthcare providers canview the sleep data using a viewer and a viewing application. The viewerand viewing applications can include mobile devices, smartphones, orpersonal computers with an installed and authorized viewing application.

As shown in FIG. 33, the server 110 can also send commands,configuration data, software updates, and the like (denoted thedownstream channel) to the sleep metering system 500 via the network 120and the wireless hub 610. This downstream channel can be used tospecifically configure the operation of a particular sleep meteringsystem 500 based on specific or dynamic conditions, such as providingconfiguration parameters for a particular sleep metering system 500,configuration for a particular subject, configuration for a particularlocation or timeframe, configuration for a particular subscriptionlevel, a dynamic re-configuration a particular sleep metering system 500based on a detected set of conditions or events in the particularsubject, providing notifications, feedback, instructions, or alerts tothe subject, and the like.

FIG. 34 illustrates an example of scoring a combined set of detectedevents and conditions in a sleeping subject, the sample scoringindicating a mild Obstructive Sleep Apnea (OSA) condition in the subjectbased on the detected respiration effort exaggeration event indicated bythe airflow and effort channels.

FIG. 35 illustrates an example of scoring a combined set of detectedevents and conditions in the same sleeping subject, the sample scoringindicating a mild OSA condition in the subject based on the detectedrespiration effort exaggeration event indicated by the airflow andeffort channels, wherein the events are more frequent.

FIG. 36 illustrates an example of scoring a combined set of detectedevents and conditions in a sleeping subject, the sample scoringindicating an abnormal pattern in the subject based on the detectedabdominal channel.

FIG. 37 illustrates an example of scoring a combined set of detectedevents and conditions in a sleeping subject, the sample scoringindicating a severe OSA condition in the subject based on the redundantpattern detected in all sensor channels.

FIG. 38 illustrates an example of scoring a combined set of detectedevents and conditions in a sleeping subject, the sample scoringindicating a moderate OSA condition in the subject based on a lack of asignificant detected snoring condition, but detection of an irregularbreathing pattern.

FIG. 39 illustrates an example of scoring a combined set of detectedevents and conditions in a sleeping subject, the sample scoringindicating a mild OSA condition in the subject based on a lack ofdetected airflow or snoring conditions, but detection of an abdominalirregular and oxygen desaturations.

FIG. 40 illustrates an example embodiment of a sleep report containing avariety of information and datasets generated using the sensor datacaptured and processed for a particular subject by the sleep meteringsystem of an example embodiment. For example, the sample sleep reportshows information datasets including: the sleep efficiency score for aparticular subject as generated by the sleep disorder diagnosis andtreatment system of an example embodiment, the particular subject'sbreathing patterns over the test period, the subject's oxygendesaturation index, BDI, a BDI severity indication, a sleep history, anda summary of the subject's sleep analysis and diagnosis. Each of theinformation datasets are based on actual sensor data retrieved from thesubject as the subject was wearing the sleep metering system 500 over atest period. As such, the information datasets generated by the sleepdisorder diagnosis and treatment system of an example embodiment arebased on the capture and processing of physical data signalsrepresenting a physical state or condition of a human subject.

The example embodiments described herein provide a technical solution toa technical problem. The various embodiments improve the functioning ofthe electronic devices and the related system by providing a system andmethod for sleep disorder diagnosis and treatment of a particular humansubject. The various embodiments also serve to transform the state ofvarious system components based on a dynamically determined systemcontext and the state of the subject being analyzed. Additionally, thevarious embodiments effect an improvement in a variety of technicalfields including the fields of dynamic data and signal processing,electronic systems, mobile devices, wearable devices, data sensingsystems, human/machine interfaces, mobile computing, informationsharing, and mobile communications.

FIGS. 41 through 44 illustrate example embodiments of the sleep meteringsystem of an example embodiment. In particular, FIGS. 41 through 44shown an example embodiment including a housing 505 containing an arrayof sensors for detecting various conditions and events in a humansubject wearing the sleep metering system 500 around their chest. Thehousing 505 is configured in an elongated low profile design to minimizethe discomfort of a subject wearing the sleep metering system 500 duringsleep.
